An EEG amplifier circuit was designed and implemented to enhance the acquisition and processing of brainwave signals. Various components, including amplifiers and filters, were integrated into the system to achieve high-fidelity signal processing and accurate EEG data representation. Oscilloscopes were utilized to validate the performance of the circuit, ensuring that it effectively amplified low-frequency signals typical of EEG recordings with minimal distortion. The circuit was powered by a regulated supply to maintain stable operation, and each stage of the design was tested to confirm its functionality and performance. The goal was to deliver reliable real-time monitoring of EEG signals, preserving signal integrity throughout the various processing stages. The system’s effectiveness was demonstrated in its ability to handle EEG signals accurately, which was confirmed through practical testing and validation procedures. The Proposed Low-Cost Optimized EEG amplifier achieved a significant improvement in performance, with its common-mode rejection ratio (CMRR) being particularly noteworthy. This result highlights the amplifier’s capability to minimize signal interference and enhance the clarity of the acquired EEG data. Overall, the implementation of the EEG amplifier circuit met the objectives of providing a robust and cost-effective solution for high-quality EEG signal acquisition and analysis, demonstrating its practical value in real-time monitoring applications.
